医学超声的主要主题是波在组织中传播的物理学。这些包括对后向散射、声速、衰减和斑点形成的基本处理。每个主题都有自己丰富的历史、词典编纂和特殊的处理方法。然而,有充分的证据表明,在与医学超声有关的所有基本现象中,幂定律关系都在基本水平上运作。本文从过去60年来的文献中总结了超声和剪切波中最重要的组织波相互作用的基本理论基础和实验证据。幂定律的共同框架可以作为主题的连贯概述,并作为改进组织表征的一种手段。
Major topics in medical ultrasound rest on the physics of wave propagation through tissue. These include fundamental treatments of backscatter, speed of sound, attenuation, and speckle formation. Each topic has developed its own rich history, lexicography, and particular treatments. However, there is ample evidence to suggest that power law relations are operating at a fundamental level in all the basic phenomena related to medical ultrasound. This review paper develops, from literature over the past 60 years, the accumulating theoretical basis and experimental evidence that point to power law behaviors underlying the most important tissue-wave interactions in ultrasound and in shear waves which are now employed in elastography. The common framework of power laws can be useful as a coherent overview of topics, and as a means for improved tissue characterization.
